Koizumi et al. [J. Acoust. Soc. Am. 82, 1179-1192 (1987)] have proposed a way to incorporate mucosal waves into previous two-mass mechanical models of the vocal folds. This was accomplished by allowing the mass of the masses to vary with time. The equations of motion Koizumi et al. used to mathematically describe this model neglected terms from the time rate of change of momentum of Newton's second law. In this letter, approximations of the magnitude of this term indicate that it must not be neglected.
小泉等人[《美国声学学会杂志》82, 1179 - 1192 (1987)]提出了一种将黏膜波纳入先前声带双质量力学模型的方法。这是通过使质量块的质量随时间变化来实现的。小泉等人用于从数学上描述该模型的运动方程忽略了牛顿第二定律中动量随时间变化率的项。在这封信中，对该项大小的近似表明它绝不能被忽略。
